SPECIFICATION forming "part of Letters Patent No. 'i'16,031, dated December 16, 1902.

Application filed March 17, 1902. Serial No. 98,574. (No model.) u

To all whom it Wray concern: Beit known that I, HENRY NORTON BUTLE GOOD, a subject of the King of Great Britain,

residing at 43 Whitehall Court, London, in

the county of Middlesex, England, have in-' vented newand'useful Im provements in Pneu matic Tires, of which the followingis aspecification.

My invention relates to improvements in pneumatic tires for the wheelsof motor-cars, bicycles, and other vehicles in which an inner india-rubber or other elastic tube is fitted around the rim of the wheel andinfiated with air under considerable pressure, an outer flexible cover being fitted around the outer part of the inated tube and having its edges strongly attached to the rim of the wheel. Y Y

The object of my improvements is to enable the pneumatic tire to be still used with sufficient efficiency after it has been accidentally` punctured.

To more fully describe my invention, reference is had to the accompanying drawings, in which the same letters designate the sameV parts in the several views.

Figure l is a vertical longitudinal section of part of a motor-car Wheel tted with Vmy pneumatic tire, the inner tube being shown infiated. Fig. 2 is a similar view showing the pneumatic tire partly inflated; and Fig. 3 is a side view on a smaller scale, partly in section, of a car-wheel fitted with my ini-- proved tire.

ais the inner inflatable tube, of india-rubber, fitted to the metal tire b, which-is itself fixed upon the wooden rim c of the wheel.Y

d is au inflating-valve of any suitablekind, and m is the usual outer` covering for the pneumatic tire. v l

n is one of a number of small cocks arranged at suitable distances' inside the tube @for dividing the same into a plurality of infiatable compartments. Thesecocks n are introduced through slit-sv or holes o in the fexible tube a `before the Y.latter is inflated and are secured to the interior surface of the tube in any suitable 'manner-such, for instance, as ley-binding the tube to the cock by means of the wire p. g y v f The plugs of the cocks n are directed toward the center of the wheel, and through the metal tire b and the wooden rim c of the wheel holes are made opposite to each cock, into which keys r can be introduced for the purpose of opening and closing the cocks n. The cocks n being all opened, the tube ct is -infiated through the iniiating-valve d and the cocks are then closed, the parts of the vVarious sections of the tube adjoining the cocks n being forced by the pressure of the air over the ends ofthe cocks and against each other, as shown in dotted lines in the right-hand part of Fig. 2 and also in Fig. 3. The left-hand part'of Fig. 2 shows one of the compartments of the tube a, partly inflated.

VIf one of the sections into which the tube ct is now'divided becomes accidentally punctured, the air will slowly escape, while the compartments will remain fully inflated and the wheel can still be used without inconvenience.

t is obvious that in order to deflate the tire it willbe simply necessary to open all the cocks and allow the air to escape through the vinfiation-valved.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent ofthe United States, is-

l. In a Apneumatic tire, the combination Awith the Youter fiexible covering, of an inner .-infiatable tube provided .with a plurality of slits, valves inserted in said slits and secured ztolthe interior surface of said tube, and means for closingfsaid valves for separating said inner tube into a plurality of inflated compart- Yingj' through holesin the metali tire b and wheel-rim c, substantially as described and shown in-the drawings. y

fIngwitness whereof I havehereunto set my hand in the presence of two witnesses.

HENRY NORTON BUTLER GOOD.
